Tata Consultancy Services did not impress me. Their recruiters were late to Skype interviews and contacted me from a different time zone without tell me. I contacted Tata from an email regarding an online career fair which was the equivalent of a chat room. I submitted the required documents and was eventually contacted by email. I asked for 1 pm interview but was asked at 11 am to interview because it happens that the recruiter lives on the East Coast and I lived on the West Coast. There was an initial phone screen with Skype. This was full of personal questions and project questions: Ex: What was your most challenging question and what did you learn from it? STAR type questions. Very relaxed and no pressure if you had interviews before. The next interview was a technical phone interview. The interviewer asked me very simple data structures and algorithms questions. This was done with a web app that allowed me to view the questions/information associated with the question. I remember there being questions on tree traversal which I easily got thanks to my data structures class.
